Approaches exploiting trait distribution extremes may be used to identify loci associated with common traits, but it is unknown whether these loci are generalizable to the broader population. In a genome-wide search for loci associated with the upper versus the lower 5th percentiles of body mass index, height and waist-to-hip ratio, as well as clinical classes of obesity, including up to 263,407 individuals of European ancestry, we identified 4 new loci (IGFBP4, H6PD, RSRC1 and PPP2R2A) influencing height detected in the distribution tails and 7 new loci (HNF4G, RPTOR, GNAT2, MRPS33P4, ADCY9, HS6ST3 and ZZZ3) for clinical classes of obesity. Further, we find a large overlap in genetic structure and the distribution of variants between traits based on extremes and the general population and little etiological heterogeneity between obesity subgroups.

The aim of this doctoral thesis was to study personality characteristics of patients at an early stage of Alzheimer's disease (AD), and more specifically to describe personality and its changes over time, and to explore its possible links with psychological and symptoms (BPS) and cognitive level. The results were compared to those of a group of participants without cognitive disorder through three empirical studies. In the first study, the findings showed significant personality changes that follow a specific trend in the clinical group. The profil of personality changes showed an increase in Neuroticism and a decrease in Extraversion, Openess to experiences, and Conscientiousness over time. The second study highlighted that personality and BPS occur early in the cours of AD. Recognizing them as possible precoce signs of neurodegeneration may prove to be a key factor for early detection and intervention. In the third study, a significant association between personality changes and cognitive status was observed in the patients with incipient AD. Thus, changes in Neuroticism and Conscientiousness were linked with cognitive deterioration, whereas decreased Openness to experiences and Conscientiousness over time predicted loss of independence in daily functioning. Other well-known factors such as age, education level or civil status were taken into account to predict cognitive decline. The three studies suggested five important implications: (1) cost-effective screening should take into account premorbid and specific personality changes; (2) psycho-educative interventions should provide information on the possible personality changes and BPS that may occur at the beginning of the disease; (3) using personality traits alongside other variables in the future studies on prevention might help to better understand AD's etiology; (4) individual treatment plans (psychotherapeutic, social, and pharmacological) might be adapted to the specific changes in personality profiles; (5) more researches are needed to study the impact of social-cultural and lifestyle variables on the development of AD.

Lorsque des poètes comme Ausone, Paulin de Noie et Claudien s'expriment en leur propre nom, une telle prise de parole n'est pas anodine et vise à générer certains effets sur le public. De manière générale, la première personne autobiographique ne doit pas être considérée comme un miroir de la personnalité du poète, mais comme une stratégie rhétorique destinée à soutenir la diffusion d'un message. Pour comprendre comment l'auteur se met en scène dans son oeuvre, il faut tenir compte d'au moins quatre paramètres : les influences génériques, la mise en scène de l'énonciation, les jeux intertextuels contribuant à façonner cette représentation auctoriale et les liens de celle- ci avec d'autres images que le poète donne de lui-même à l'intérieur d'un plus large corpus de textes. En comparant les personae mises en scène par ces trois écrivains de l'Antiquité tardive dans différentes formes littéraires (lettres versifiées, discours à visée didactique, exordes, éloges d'autrui), cette thèse de doctorat démontre que l'emploi du « je » est généralement lié à la recherche de persuasion et que ces figures littéraires ont en commun plusieurs traits caractéristiques qui offrent un point de départ à des développements variés.
